In the textile and apparel industry, rib knitted fabrics are widely used in a variety of clothing designs due to their excellent elasticity and unique texture characteristics. However, high-quality yarns and exquisite weaving technology are not enough to fully guarantee the final quality of the fabric. As an important part of the fabric production process, the post-processing process plays a vital role in improving the performance of Knit rib fabrics, improving its appearance and feel, and ensuring the stability and durability of the product.
Dimensional stability and morphological control
The length setting (tenting) and heat setting treatment in the post-processing process are key links to ensure the dimensional stability of Knit rib fabrics. During the tentering process, the fabric is slowly stretched to a predetermined size. This process not only eliminates internal stress, but also effectively adjusts the shape of the warp and weft yarns in the fabric, ensuring uniform width of the fabric and correcting the weft skew. Heat setting is to keep the fabric in a fixed shape and size under specific temperature and pressure, thereby further consolidating the tenter effect and significantly improving the dimensional stability of the fabric. These treatments can effectively reduce possible deformation of the fabric during subsequent processing or wearing, ensuring that the shape of the garment remains stable.
Elasticity and resilience optimization
Knit rib fabric is famous for its excellent elasticity, but the elasticity of fabrics without post-treatment may be reduced after long-term use or washing. The pre-shrinking treatment in the post-processing process effectively reduces the shrinkage of the fabric after being immersed in water through physical methods, significantly reducing the shrinkage rate and further improving the elasticity of the fabric. In addition, the use of specific chemical finishing agents, such as softeners or elastic finishing agents, can improve the elasticity and resilience of the fabric so that it can better meet the high requirements for elasticity and comfort in clothing production.
Improved look and feel
The post-processing process can also significantly improve the appearance and feel of Knit rib fabrics. Through calendering, electro-optical or embossing treatment, the plasticity of fibers under hot and humid conditions can be used to flatten the surface of the fabric or form patterns, thereby improving the gloss and aesthetics of the fabric. Sanding, raising and shearing treatments give the fabric a soft touch and rich surface texture, enhancing the warmth and comfort of the fabric. These treatments not only enhance the visual and tactile experience of the fabric, but also enhance the fashion and quality of the clothing.
Improved durability and performance
Post-processing also plays an important role in improving the durability of Knit rib fabrics. Through chemical treatment, the fabric can effectively resist the corrosion of fibers by sunlight, atmosphere or microorganisms, thus extending the service life of the fabric. At the same time, specific finishing processes are used, such as anti-wrinkle finishing, water-repellent finishing or anti-bacterial and anti-odor finishing, to give the fabric specific protective properties and special functions, making it more adaptable to diverse use environments.
